Question : Are you getting the following errors while you are installing CAB (CompositeUI Application Block) on your Vista box?

Here is the Solution for you.

The shortest answer is “turn off UAC before installing CAB”.

Please read the following if you dont know how to do it.

• Go to “Control Panel”

• Go to “User Accounts and Family Safely”

• Click “User Accounts” as picture below

• Click “Turn User Account Control (UAC) on or off”

• Uncheck “Use User Account Control (UAC) to help protect your computer” and Click “OK” button

Then you may start to install CAB framework in your Windows Vista. I hope it would help. Feel free to let me know if you have any problem. I have tested this instructions on my Windows Vista Premier Edition. It works great.. Dont forget to turn on UAC once done.
